DEGENERATION OF SL(n)-BUNDLES ON A REDUCIBLE CURVE

چکیده
It is a classic idea in algebraic geometry to use degeneration method. In particular, it achieved successes recently in the studying of moduli spaces of vector bundles (See [Gi], [GL1], [GL2], [NR] and [S1]). In connection of string theory, it needs also to study the degeneration of moduli spaces of G-bundles for any reductive algebraic group G (See [F1],[F2]). Let X → B be a proper flat family of curves of genus g such that Xb (b 6= 0) smooth and X0 a semistable curve. It was known that there exists a family MX (G)0 → B0 = B \ {0}

Surface group representations to SL(2,C) and Higgs bundles with smooth spectral data
Let Σ be a closed, oriented surface of genus g ≥ 2. In this short note we answer a special case of the following question posed by Nigel Hitchin: which representations ρ : π1(Σ) → SL(n,C) correspond to Higgs bundles which lie outside the discriminant locus of the Hitchin fibration for some Riemann surface structure on Σ? For example, the Higgs field for a unitary representation (i.e. one whose ...
متن کاملMODULI SPACES OF SL(r)-BUNDLES ON SINGULAR IRREDUCIBLE CURVES
One of the problems in moduli theory, motivated by physics, is to study the degeneration of moduli spaces of semistable G-bundles on curves of genus g ≥ 2. When a smooth curve Y specializes to a stable curve X , one expects that the moduli space of semistable G-bundles on Y specializes to a (nice) moduli space of generalized semistable G-torsors on X . It is well known ([Si]) that for any flat ...
متن کاملOn the reducible $M$-ideals in Banach spaces
The object of the investigation is to study reducible $M$-ideals in Banach spaces. It is shown that if the number of $M$-ideals in a Banach space $X$ is $n(<infty)$, then the number of reducible $M$-ideals does not exceed of $frac{(n-2)(n-3)}{2}$. Moreover, given a compact metric space $X$, we obtain a general form of a reducible $M$-ideal in the space $C(X)$ of continuous functions on $X$. The...
متن کاملTheta Functions for Sl(n) versus Gl(n)
Over a smooth complex projective curve C of genus g one may consider two types of moduli spaces of vector bundles, M := M(n, d), the moduli space of semistable bundles of rank n and degree d on C, and SM := SM(n, L), the moduli space of those bundles whose determinant is isomorphic to a fixed line bundle L on C. We call the former a full moduli space and the latter a fixed-determinant moduli sp...
متن کاملA Gieseker Type Degeneration of Moduli Stacks of Vector Bundles on Curves
We construct a new degeneration of the moduli stack of vector bundles over a smooth curve when the curve degenerates to a singular curve which is irreducible with one double point. We prove that the total space of the degeneration is smooth and its special fibre is a divisor with normal crossings. Furthermore, we give a precise description of how the normalization of the special fibre of the de...
